Hi @niceszett
From your videos, this looks like a driver problem almost identical to that reported for AMD Radeon graphics recently. The AMD RX Vega driver could have the same issue, the fact that its an external GPU could also be a cause.
I have a diagnostic mode in development but it isn’t ready yet. Meanwhile you might be able to isolate the OpenGL/DirectX linkage part of the driver by going back to the earlier 2.006 demo programs.
You only need to download three files directly :
SpoutSettings
Demo sender
Demo receiver
Run 2.006 SpoutSettings. Check “CPU” on and OK to save. Run the 2.006 demo Sender and Receiver together. These will be very slow but might confirm an issue with the OpenGL/DirectX texture functions of the graphics driver. The Max/Msp plugin does not support CPU share mode but might add to the test, as might TouchDesigner.
When you have finished the tests, run the 2.007 version of SpoutSettings aagin, click “Reset” and OK to save.
The fact that TouchDesigner works OK is a lead and I will follow that up.
